Disclosed is the use of glycol ether aryl ester plasticizers as viscosity reducing agents in plastisols comprising di(2-ethylhexyl) terephthalate, 1,2-cyclohexane dicarboxylic acid diisononyl ester, or diisononyl phthalate as the primary plasticizer. The glycol ether aryl ester plasticizers improve viscosity and viscosity stability while maintaining or improving plastisol properties such as Shore A Hardness and fusion time.
本发明揭示了在含有二(2-乙基己基)对苯二甲酸酯、1,2-环己烷二羧酸二异壬酯或异壬酸酯类主要增塑剂的浆料中,使用乙二醇醚芳基酯增塑剂作为粘度降低剂。乙二醇醚芳基酯增塑剂提高了粘度和粘度稳定性,同时保持或提高了浆料的性能,例如Shore A硬度和熔合时间。
